To all whom it may concern.-

Be it known that I, FRANK Kxonsnoon, a. citizen of the United States of America, and a resident of Dayton, county of Montgomery, State of Ohio, have invented certain new and useful In: rovements in Paper Boxes. of which the ollowing is a specification.

M invention relates to a box formed irons blanhs of paper of a heavy and of a light texture laid one upon the other and folded up together, which keeps its contents roof against both a dry and a moist atmosp ere. Its object is to provide a means for facilitating the folding of the light and the heavy paper together to form the box.

A further object is to provide a box which is more proof than those now in use against the varying conditions of the atmos here.

These objects are attained by t no means shown in the accompanying drawings, in which- Figure 1 is a plan view of a blank of heavy aper shown in full line, and in dot-and-dash inc s owing the blank of light paper. Fig. 2 is a similar view of the same after the heavy blank has been folded upon itself, the linin -blank of light paper being shown here in fu l lines. Fig. 3 is a. sectional view taken upon line 1) o of Fig. 2. Fig. 4 is a perspectwe view of the box before the cover is closed. Fig. 5 and Fig. 6 show plan views of modified forms showing a different manner of holding the light nper and the heavy together. Fig. 7 and ig. 8 are similar views of another modified form. Fig. 9 is a detail View of a part of the'exterior blank of heavy Fa er, showing the means of securing the 1g ter spot in place. Fig. 10 is a sectioncl View ta en upon line 2 z of Fi 8. Fig. ii

is a perspective view showing t 1c first stop in folding blanks upward to form the box.

1 Figs. 12 and 13 are perspective views illusof heavy paper which forms the exterior of trating the second and third steps in the foldin Fig. 14 is a sectional view of the comp eted box. 1 r

Referring to the parts, the primary blank the box is ,of the same shape in all of the modifications. scored to form four central rectangular figures or sections -to wit the bottom section A, the front and rear side sections 3 and G,

- and the top section B. At each end. of the central sections are extensions integral therewith, separated by scoring only into end 880-. tions'corresponding in width to the contigolong the line a. and the ends l; i) being This part of the blink 'is' nous central sections. Thus a a represent "'lociring slitb and c c represent the end sections in line with the front side section 0, each of which is rovided with a lockingtongne c formed a substantially diagonsl out which exten s from the outer edge of the end section adjacent to one of the central end sections a a to a point near the center of section a or 0. Each of the end sections 0 c is also )rovided with a. score a 0, extending from the termination of the cut above referred to ad'acent to the center of the section diagonaly to the adjacent corner of bottom section A; as shown in Fig. I. Itwill thus be seen the: the lateral integral end folding sections are three in number, the con 7 trel end sections a a being scored diagonally" and the others provided with the described interlocking.devices-to wit, the slit 6 and tongues c" Along the alined edges of the front side section C and end sections c c are" folding fispsc, c. and c, and a slit a is provided between the front side section'C and flap c to receive a securing flap or card, formed integrall with the ooveror top section D. To fol up this blank to form the exterior of the box, the blank is bent along the line dividing side B from bottom A, the ends a a being doubled upon themseilves ent at right angles along the line dividing-them from side B, the exterior then resenting in appearance the form shown in ig. '1 i. The folded ends d a are then bent upward against ends b a, as shown in Fig. 12, and then the {rent side 0 is bent upward, the'end 'c c doubling along the score of c and the ears c being inserted into the slits b, as shown in Fi 4. It is noted that the central on: sections wc'whco the box is folded lie between the interlocking end sections.

I will now describe the means for holding the light pafper lining in place u on the heavfi paper and or causing it to fol readily wit the some.

' In Fl .1 I hm snom formed new with the leak of heav paper just descri -and connected to 'ifjbf'small tongues d d 9.

seconds. blank consisting of the following guts-v12, a rectangle D eorrcsponding eel a. rectangle B corresponding with B,

tangles b b at its ends corresponding to b b, a rectan le A corresponding to a, and a rectangle with trian lar portions 0 c". This blank is to be fol ed about the line be -tweendparts D D, so that the parts just describe lie flat u on their corresponding parts in the primary lank, the edges of trian ular portion c c" registering with the scored ines c 0. Between the hea paper a rectangular blank of light pa er is placed, which is of a width equal to t e width of the blanks of heavy paper and of a greater length thanthey, so as to extend beyond them, as shown m Fig. 1. In folding up the blank to form the box the the exterior of the box are to d in the same manner as afore described. The secondary blank of heavy paper holding the light paper flat upon the primary blank has the folding lines in the secondary blank re isterimg with the folded lines in the primary li lank, and the light paper is caused to fold similarly to the hea paper. Thus when in the first step side is turned upward about the line between it and bottom A the secondary blank and the light aper likewise fold uabout that point, and when ends 11 b are out inward the light paper is caused to fold along the lines a, the secondary blank not havin $12 part to correspond with the ends a a en the folded parts a a are turned upward ainst the ends I; b and as the ends 0 c are fol ed a ainst the ends a a, the light paer is folded along the line registering with inc 0 c and with the edges of the triangular flaps 0 0", which register with the line c a. After the ears '0' have been inserted into the slits b, as shown in Fig. 13, the box is ready to receive whatever is to constitute its contents, such as-crac'kers, cakes, &c.

In closing the box the inner cover D is first turned down over the contents, end he s c c" arethen' turned down, causing the lig t paper to be folded inward, leaving flaps e e' out and rear, as shown in Fig. 4, then flap c is turned downward ,carrying flap e down, and tongue d is inserted into the slit 0 to close the box.

It is seen with this construction no former isneeded to hold the light aper in place to cause it to fold in the desire manner, the secondary blank holding it in place and causing it to fold along the lmes desired. It is seen likewise that with the box just described there is a complete interior and an exterior box of heavy paper, between which lies a complete box 0 light paper, so that the contents of the box are entirelyprotectedagainst the eflects of varying conditions in theatmosere. The modifications shown in 7 to 10, re ectively differ from that st described on y m the following parts. be second blank instead of being secured to the mmary blank by tongaeasuchas tongues d,

parts of the heavy dpaper forming (shown in Fig. 1) has cut into ends ll 6 of the part B tongues 1) 6, which pro'ect down through slits in the light paper into the slits b, formed in the ends of portions b b, as shown in Fig. 10. The shape of the secondary blank is the same in this modification as in that aforedescribed. The manner of folding the same together and the form of package resulting is the same as just described.

In Figs. 5 and 6 I have illustrated a modification of the secondary blank which omits the parts A C described in the modifications already disclosed, and I fasten the parts together b clips F F, assin down through the parts 3 b, throug the 1 ht paper, and throu h the end I) b. The f0 ds in the primary lank are made in same manner as in the modifications already described, and the secondary blank holds the light paper in place upon the primary blank and causes it to ollow the same folds as occur in the light pa er in the other modifications.

t is seen that besides facilitating the folding of the parts the secondary blank affords integral ends to the interior of the box, so as to cover any fissures which may occur in the interlocking ends of the primary blank, that this, together with the intimate contact with one another with which these inner ends hold the light paper and the primary box, renders the same impervious to the atmosphere, and likewise that when the contents of the box or a portion thereof are removed therefrom that the light paper does not become crumpled, but is retained in shape by the secondary blank.

What I claim is 1. A blank for a aper box comprising among its members a at mainblank suitably cut and scored, a former-blank superposed upon the main blank and having out and scored portions adapted to register with similar portions of the main blank and a lining consisting of a separate sheet of thin paper blank and a linmg consisting of a separate piece of thin paper of greater area than the ormer-blank interposed between the main blank and the former-blank the said main blank and the former-blank connected at separated points to hold them in re a tion, whereby when said blank is folded the former-blank serves as a former for the and remains a permanent part of the box when iolded, substantially as described.

5 main blank and having cut and scored 'ortions adapted to register with portions 0 the main blank, a lining consisting of a separate sheet of thin paper interposed between the said main blank and the former-blank and means for connecting said main blank, lining and former-blank at separated points only to hold them together, with the main blank and former-blank in registration, whereby when said blank is folded the former-blank serves as 5 a former for the lining and remains a permanent part of the box when folded, substantially as described.

4. A paper box comprising among its members a main blank, cut and scored to provide,

a rectan ularportions forming the top, bottom and sides of the box and a laterally-extending integral portion at each side, so arated only by scoring, into sections adapts to interfold to form t 1e ends of the box, ,one of said into- 5 gral sections being scored diagonally and the others of said sections being provided the one with a slit and the other with a lockingtongue, a lining of thin paper, and a formerblank of less area than the lining and main 0 blank and provided with top, bottom and side portions scored to register with the main blank and having lateral portions adapted to interfold between the folds of the end portions of the main blank and force the linin to con- 5 form to such interfolding, where y' said former-blank serves as a former for the lining duri the folding.

5.? paper box comprising among its members a main blank out and scored to rovide D rectangular portions forming the top, ottom and sir es of the box and a laterally-extending integral portion at each side, so arated only by scoring into sections adapts to interfold to form t e ends of the box, one of said intergral sections bein scored dia onally, alining of thin paper, an a former-blank of less area than the lining and main blank and provided with top, bottom and side portions scored to register with the main blank, and having latoral ortions adapted to interfold between the olds of the end portions of the main 7 blank and force the limng to conform to such interfolding, whereby said former blank serves as a former for the lining during the fol operation and remains a permanent art 0 the box when folded, substantially'as ascribed.
